Abstract (en)
The present disclosure relates to an anti-reflective film comprising: a hard coating layer; and a low refractive index layer, wherein a particle-mixed layer containing both hollow inorganic nanoparticles and solid inorganic nanoparticles and having a thickness of 1.5 nm to 22 nm exists in the low refractive index layer, and wherein the anti-reflective film has a ratio of the reflectance at a wavelength of 400 nm to the reflectance at a wavelength of 550 nm of 1.3 to 2.7, and a polarizing plate, a display device, and an organic light emitting diode display device comprising the anti-reflective film.
